QUALITATIVE DATA COLLECTION . The aim of this session is to enable you to: • justify decisions about sampling select and apply an appropriate method of data collection construct questions for qualitative data collection and elicit high quality responses
The aim of this session is to enable you to:
• justify decisions about sampling
Sampling is not statistically representative but ‘purposive’ or ‘theoretical’, i.e. you sample people who will provide information that serves the purpose of your research.
Do you need to sample people:
Non-directive questions designed to elicit interviewee’s perspective (suitable for qualitative research).

Good communication skills essential:
- neutral prompts such as ‘mmm’ ‘I see’, ‘that’s interesting’, ‘can you tell me more?’

Focus groups: group discussion ‘focused’ on particular topic
Imagine you want to carry out video-recorded interviews with men unable to work due to back pain, in their own homes. Anticipate the difficulties you may encounter and how you will resolve them. (For discussion in tutorial groups)
1. Practical difficulties
2. Risks to your interviewees or yourself
3. Ethical issues
